Numerical Simulation of Indirect Tensile Test Based on the Microstructure of Asphalt Mixture
Publisher: American Society of Civil Engineers
Abstract: Indirect tensile (IDT) test is widely adopted to evaluate the anticracking performance of hot-mixture asphalt (HMA) at intermediate and low temperatures. This paper presented an approach to simulate the IDT test based on ...
Modification Mechanism of Using Waste Wood–Based Bio-Oil to Modify Petroleum Asphalt
Publisher: ASCE
Abstract: The aim of this research is using a waste wood–based bio-oil as the modifier of petroleum asphalt and analyzing its modification mechanism. The four components, infrared spectrum, and molecular weight distribution analysis ...
Microscopic Analysis of Aging Effects on the Adhesion Properties between Asphalt and Mineral Aggregate
Publisher: American Society of Civil Engineers
Abstract: This research investigated the effect of aging on the adhesion properties between asphalt and aggregate at the molecular level. Based on the molecular dynamics simulation method, the adhesion characteristics of asphalt ...
Restoration Effect of Waste Cooking Oil on the Colloidal Structure of Aged Asphalt
Publisher: American Society of Civil Engineers
Abstract: The aging of asphalt is accompanied by alterations in its colloidal structure that in turn leads to premature failure and/or deteriorates the performance of asphalt binders. The use of rejuvenators to restore asphalt binder ...
Effects of Physio-Chemical Factors on Asphalt Aging Behavior
Publisher: American Society of Civil Engineers
Abstract: Based on an accelerated asphalt-aging test in the laboratory, the authors evaluated the physical and chemical properties of asphalt at different aging times and temperatures for this paper. They evaluated the properties ...
Comprehensive Performance Evaluation and Cost Analysis of SBS-Modified Bioasphalt Binders and Mixtures
Publisher: American Society of Civil Engineers
Abstract: Developing new sustainable materials such as bioasphalt has become a research trend in recent years. In this study, bioasphalt modified with the addition of styrene-butadiene-styrene (SBS) was investigated to research ...
Characteristics of Latex-Modified Bitumen Prepared via Foaming Technique Using Water and Diluted Methanol
Publisher: ASCE
Abstract: The ability of latex to notably improve the performance of asphalt pavements has established the material as a favorable modifier in asphalt systems. However, the high viscosity of latex-modified asphalt (LMA) binders ...
Test Method to Evaluate the Tensile Performance of Hyperelastic Binders with Large Deformation
Publisher: American Society of Civil Engineers
Abstract: Airport pavements, especially runway holding positions, are susceptible to high shear forces and thus rutting damages under the coupling effect of heavy aircraft loads and high temperatures. Pavements produced with commonly ...
Characterization of the Distress Modes and In Situ Material Properties of Highway Asphalt Pavement with Long Service Life
Publisher: American Society of Civil Engineers
Abstract: A 36-year-old, heavily trafficked highway asphalt pavement was analyzed in detail. The variation in structural capacity was assessed by a falling-weight deflectometer (FWD). Trenches were cut to examine the distresses in ...
